black holes They are among the most mysterious objects in the Universe. Since opening in 1964 Swan X-1, many of them were discovered with very different characteristics. We even managed to photograph the silhouettes of two of them. However, with each new discovery, questions continue to arise. Now a group of scientists from Australian National University discovered the brightest black hole and glutton and, as always, questions arose that had not been raised before.
This black hole is located at the center of a quasar galaxy, which may have been formed 1.5 billion years after the Big Bang. As always happens with very distant galaxies, we see it not as it is now, but as it was shortly after its birth. This is because its light takes many years to reach us. In particular, it is estimated that its light lasted about 12 billion years in reaching telescopes that made it possible to observe them. This means that it should still be a small galaxy, but not only is it large in size, but its black hole is more than supermassive. It is a colossal black hole with a mass equivalent to approximately 17,000 million times more than our Sun.
This will become clearer if we consider that he devours solar mass full. It is precisely because of the rate at which it consumes matter around it that this very bright black hole is at the limit of its evolution, where no other black holes have been observed before. This makes it very interesting for scientists, although it raises doubts about the knowledge they already have about objects of this type.
Black hole is so bright it’s at its limit
When a large star runs out of fuel to keep it burning, it explodes and collapses, causing ultra-compact black hole. This new object is so massive that its gravitational pull affects everything that comes within a certain distance of it, known as the event horizon. Not even light can escape his gluttony.
For this reason, black holes are always surrounded by a disk of gas and dust, which approaches them until it falls into their depths, as if attracted by the center of the funnel. The thing that’s coming towards him moves at high speed creating a lot of friction between its particles. And it is this friction that makes a black hole bright.
However, in what has just been described in Nature Astronomy, something special is happening. It feeds at such a breakneck speed that it has become the most flamboyant engro-hole ever described. Its brightness is so high that it reaches something known as Eddington limit. Above this point, the brightness is so high that radiation pressure can push matter beyond the event horizon, preventing it from feeding further.
Radiation pressure is the pressure created by any electromagnetic radiation on a surface. In this case, the brightness itself, resulting from the friction of matter, will be radiation, which will affect precisely that dust that is attracted to the center.
Perhaps there are more
These scientists believe that although it is the brightest black hole ever seen, There must be more like him.
For now, until some more are discovered, this has become a good subject to study as it represents the end of black hole evolution. How he got there so quickly remains a mystery. But it’s best to go step by step. At least scientists have something to analyze.
